The method of emission inspection for In-use diesel vehicles has been Engine speed type Lug-down 3mode. This method could bring damage to decrepit vehicles under high speed and High load condition and it could not apply the driving pattern on the road. For these reasons, this study has started to create new emission inspection which is appropriate for Korea"s road infrastructure. KD 147 would be applied to Light-duty diesel vehicles from July 2010 after model operations. Therefore, this studies has investigated new emission inspection system for Heavy-duty diesel vehicles, except for Light-duty diesel vehicles.

Current emission inspection procedure for the diesel vehicle is Lug-down 3 mode. It is effective for high-emitting vehicles as vehicles are inspected under the high-load and high-speed condition, but it has weak points. It does not reflect the traveling pattern such as acceleration or speed reduction, and there is possibility to be manipulated before and after the inspection. In particular, in case of some older vehicles, it makes some damages during the inspection. As it also makes noise and dust, we conduct this research to improve the related problems and examine the new emission inspection.

In-used 2-wheel vehicles have been used as important means of transportation, but the exhaust gas management system has been left without any alternative. In particular, some two-wheeled vehicles and no catalyst, 2-stroke engines using a mixture of fuel oil combustion emissions, despite not established acceptance criteria and test system does not provide a comprehensive management system is required. Thus, throughout the country and abroad to do research to establish the appropriate emissions test, and to set emission standards and emissions inspection program to review the feasibility of introducing, through maintenance and repair methods before and after the comparison test was presented.

Korea has operated separately in each periodic vehicle inspection and periodic vehicle check system for efficient management of in-use vehicle. Periodic inspection is a system that for all vehicles, evaluate the suitability of the road driving without the disassembly and maintenance of the vehicle, and periodic check is a system that for the commercial vehicles, through the disassembly and maintenance of the vehicle, implement to ensure the safety and performance of vehicle. However, periodic check has been pointed out steadily because it had slipped into the institutional formal system to weight the economic burden of the public. Therefore, in this study, we would present the suggestion to integrate periodic inspection and periodic check through the analyses on domestic and foreign status of periodic check and the deducting problem. In particular, whereas periodic vehicle inspection has been implementing in all 34 countries member countries on Organization for Economic Cooperation and Development(OECD), periodic check has been implementing in japan, only one in the world. So, we compared and analyzed the items of periodic inspection and periodic check, and we presented the suggestion on the integration of two systems. In addition, another purpose in this study is to enhance the vehicle safety and to reduce burden on the public by presenting the compensation plan of the integration of two systems.
